Letters Patent N 96,091, dated October 26,1869.

IMPROVEMENT EN MACHINES FOR. MAKING RPE-MOULDINGS.

The Schedule referred to in these Letter Patent and making part of theame.

To all 'whom it may concem Be it known that I, CHARLTON EDEN, ofIndianapolis, in the county of Marion, and in the State of Indiana, haveinvented an Improved Circular Moulding-Machine; and I-do herebydeclarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the-letters andgures of reference marked' thereon. l

The nature of the invention consists in the construction of theinachinehereinafter described, for the purpose of cutting straight anannnlarrope-xnoulding,

said machine to be made of wood, iron, and steel, or any other suitableand convenient materials.

To enable others skilled in the art to make and use my saiddnveution, Iproceed to describe it more fully, as follows:

Figure 1, of the accompanying drawings, is a perspective view of saidmachine.

M N is a straight moulding, in the position in which it'is cut by thesaid machine.

M' N is -an annular moulding, in a like position.

R. is the rest, in which said mouldings are held while being cut.

T is the guide.

O, the cutter-shaft.

K K, the bearing in which it runs.

P, a pulley, fordriving, and

Q, the cutter, whose edge is of the segmental circular form representedin section by Q, of Figure 3.

A B C D E F G H I is the frame on which the de vice sets, and is of theform there represented.,

S is a slide, which moves up and down on A B, for the purpose ofadjusting the size of the moulding to the position of the cutter.

The cutter reaches the moulding by passing into a notch, represented byQ Q" Q', of Figure 2 of the accompanying drawings.

To use my said machine, the operator takes a cyl-` indrical piece ofwood, either straight or annular, of

convenient size, and'having properly adjusted the machine to it, pressesit into the rest R until the cutter` strikes it. It is then turnedslowly, and pressed forward until-it reaches the guide T, which, passinginto the furrow made by the cutter, will, if the cylindricall piece ofwood be turned slowly, by reason of its shape, (a segment of a femalescrew,) carry the wood so that the cutter will shape the furrow like/the space of a round-threaded screw.

This may be repeated on another and another side, until the moulding isvcomplete, making as many strands in the rope-moulding as may be desired.The cutter makes the adjacent sides of two adjacent strands each timethe wood is run through.

By reason of the form of the frame A B C D E F G H I, one half of acylindrical ring may be turned round and round in the rest R asconveniently as a straight cylinder.l

The guide T, which is a segment of a female screw, may be either rightor left-handed. `\If it be righthanded, the wood is turned to the right,and a righthanded moulding produced. If it be left-handed, the wood isturned to the left, and a left-handed moulding produced. A cutter may beplaced ou either end of the shaft O, and the same effect produced.

What I claim, and desire to secure by Letters Pat- 1. The combination ofthe rest It, the guide T, the bearing K K, the shaft O, and the pulleyI, whenthe same are combined and used for the purpose of cuttingrope-moulding, substantially as herein set forth.

2. The combination ofthe -rest R and. guide T with the cutter Q,substantially as herein set forth.

3. The combination of the rest R, the slide S, and theguide T,substantially as herein set forth.

In testimony that I claim the foregoing specification,

I have hereunto set my hand, this. day of May,

` TOHARLTON EDEN.
